Installing MariaDB Community Server 10.5 on Ubuntu 20.04 LTS

In this article, we are installing MariaDB Community Edition on Ubuntu 20.04 LTS, and, a in future post we will configure replication.

I followed these steps from the MariaDB docs, here:

But first, since this is a new server, let's upgrade it.

Update the package lists for upgrades for packages that need upgrading.

Once we know that it's running we can connect to it.

ubuntu@ubu2004mariadb02:~$ sudo mariadb

and we can enable it so next time we reboot the server, the MariaDB service will start automatically.

ubuntu@ubu2004mariadb02:~$ sudo systemctl enable mariadb

As mentioned, in a future post we will configure replication.
